Abstract: A protection system includes a mount for attachment to a wear panel of equipment. The mount includes a first portion which engages the wear panel to be protected and a second portion extending from the first portion which engages an adjacent face to be protected. The second portion has a passage which allows sliding movement of a bolt along the passage. A wear part is releasably mounted to the mount and has a first portion that slidingly engages the first portion of the mount and a second portion that engages the second portion of the mount. The second portion of the wear part has a passage arranged to align with the passage through the second portion of the mount when the wear part and the mount are engaged. A bolt extends through the aligned passages to secure the wear part to the mount via a locking member.

Abstract: An abrasion wear resistant distributor plate assembly is mountable to protect a rotor within a vertical shaft impact crusher for material fed into the rotor. A distributor plate is configured to be resistant to the operational abrasive wear resulting from contact with a flow of crushable feed material through the crusher rotor. Attachment components are provided around a perimeter of the plate to facilitate mounting and decoupling of the plate at the rotor during servicing or replacement procedures.

Abstract: A hammer assembly that will mount in a grinder/shredder/hammer mill type machine. A tool holder is milled with dovetail/angular slots along each side of the hammer tool holder, which allows milled blade to slide in to place and be securely held in position. The simple milled slot located in the middle of each blade that allows a single mounting block/bolt to securely hold each blade in position. This results in the ability to rotate and/or interchange blades. The tool holder allows single or multiple blade/hammer inserts to be installed without having to remove a hammer pin, so the tool holder stays in the machine, and the blades can be easily removed. This arrangement allows the tool holder to stay in place, and enables the simple removal of a single bolt and retention block and then flip or rotate the hammer to get additional wear surfaces or install new blades.

Abstract: The present invention relates to rollers subjected to wear conditions and surface reinforcements for such rollers. More specifically, the present invention relates to the orientation of projections on the rollers or surface segments of such rollers. In one embodiment, the roller includes a hub. The roller also includes a plurality of removable surface segments attachable to the hub so as to form a layer around the hub. Each surface segment has two opposed sides and an exterior surface. The spacing between projections across the exterior surface decreases from each of the opposed sides to an intermediate point between the opposed sides.
